DEM/CFD simulation to minimize dust and biomass debris on farm equipment systems

Dust and biomass debris have serious negative effects on the performance of material handling farm equipment, such as reduced efficiency, increased maintenance costs, and heightened fire hazards. However, there is a lack of understanding of dust and debris generation and dispersion within farm equipment. CNH Industrial is searching for innovative solution for dust and biomass debris control in farm equipment. On this basis, this study aims to develop an integrated DEM and CFD model for simulating the behavior of dust and biomass debris generated during harvest, and use the model to optimize the design of agricultural harvesters to improve the efficacy of in-harvester dust and biomass debris removal. The rheological and aerodynamic properties of dust and biomass debris will be measured at CNH facility, and the proposed model will be validated with small scale lab experiments as well as in-field experiments. CNH Industrial will benefit from training highly qualified personnel, technological advancements, and product optimization in terms of dust and biomass debris minimization.
